I'm excited about this service. You can convert your files, cover and all, into Kindle and ebook formats easily, and for free.
I've been struggling with how to do this. CreateSpace charges for the service, and I, being a cheapskate, have been working on a free solution. And then wouldn't you know it, one of my buddies just does it for me on the side using Calibre. It's nice having friends who actually know what they're doing. Now I need to make a lawyer friend and a mechanic friend.
